How often do you back up your pc files or complete hard drive contents? Most dont do it at all till its too late and then wish they had.
To get you started how about backing up your outlook express mail data, you would be lost without it wouldnt you.
This helpful page shows you how to use XP's File and Settings Transfer Wizard to copy the data from OE to somewhere else just in case ;)http://www.iopus.com/guides/free-oe-backup.htm
Here's another Free method that stores all the files seperately so you can just put back what you need.http://www.softwarepatch.com/software/oebackup.html
Free and here
Hope this helps someone.
